Title: Method of constructing a tunnel tube or the like
Inventor: WAGNER HARALD DIPL ING DR
IPC: E02D29/055
Filed: 1986-03-06
Abstract: To construct a tunnel tube (1), an arched roof (2) is constructed on the base of an open trench and then a hollow space is excavated underground underneath the roof (2). During the excavation of the hollow space, lateral-pressure abutments (4) of the roof (2) which are accessible from below are pushed into the arches (9) and anchored. Until the side walls (3) of the tunnel tube (1) withstanding the rock pressure are constructed, these lateral-pressure abutments (4) secure the hollow space and underpin the roof (2), the feet (5) of which have been produced in a thickness which corresponds to at least the thickness of the side walls (3) of the tunnel tube (1) and the thickness of the hollow-space side-wall sheeting (7) containing the arches (9). <IMAGE>

Title: Device for connecting at least one loading plane of a vessel or the like to at least one removal path or plane
Inventor: SPRINGHORN MANFRED DIPL ING
IPC: B63B27/14
Filed: 1986-03-20
Abstract: The problem of creating a connection between all types of vessel and a shore-side plane which enables vehicles to drive onto the vessel from the shore frequently occurs. For such vessels, which have several loading planes (19, 20) arranged one above the other, the invention proposes a device which has a ramp (13) composed of two parts, namely the ramp sections (14 and 15). These ramp sections (14, 15) connected to one another in an articulated manner and to the vessel are pivotable in such a way that in each case one of the ramp sections (14 or 15) can alternatively be taken to roughly the same level as the top loading plane (19) or the bottom loading plane (20).   <IMAGE>

Title: Method of placing concrete in formwork for constructing a tunnel lining in cast-in-situ concrete, and devices for carrying out the method
IPC: E21D9/08
Filed: 1986-03-26
Abstract: In the construction of tunnel linings in cast-in-situ concrete which is pressed into a hollow space which is formed by the excavated areas of the rock, inner formwork and end formwork, plungers (15) are pushed forward in the concrete-feed nozzles (9) during an interruption in the concreting operation up to the level of the end face of the diaphragm (7) for cleaning and remain there until the lining concrete has hardened in order to be able to continue concreting in a troublefree manner after stoppages. When the concreting operation is resumed, at least one nozzle (9), which is movable relative to the end formwork (6), and the diaphragm (7) firmly and tightly connected to it at its outlet opening are partly removed from the front of the hardened lining concrete. This results in a space of favourable shape for the concrete flow. This space can be immediately injected with fresh concrete without problem and allows no hollow space to develop into which water or soil particles from the excavated areas can penetrate. A device (16) of appropriate design enables the method to be carried out. <IMAGE>

Title: Cylindrical hopper for storing bulk materials, in particular cement clinker
Inventor: SCHERR PIUS
IPC: B65G65/32
Filed: 1986-07-18
Abstract: The cylindrical hopper serves for storing bulk materials, in particular cement clinker, and comprises an interior which is subdivided by at least one closed wall (6) into at least an outer container (5) and an inner container (7) for receiving different bulk materials. An upper device (23) supported by the inner container allows selective loading of the containers (5, 7). A hopper design which is of particularly simple construction and is easy to maintain results if the inner container (7) bears a collar plate (14) which projects with its outer rim (15) beyond the wall (6) of the inner container. Provided in the projecting annular region is a plurality of outer openings (17) which determine the height of the heap in the outer container (5). It is possible to walk on the collar plate (14) outside these openings. The projecting annular region bears the upper end of the roof elements (19) covering the outer container (5). Assigned to the projecting annular region are brackets (20) which serve for support and are arranged offset relative to the outer openings (17). <IMAGE>

Title: Method and apparatus for the production of helical toothing by cold forming
Inventor: DERIAZ DANIEL
IPC: B23F5/20
Filed: 1986-09-23
Abstract: Helical toothing of high precision is obtained with the Grob method, which is known per se, the workpiece (W) being rotated continuously and producing a symmetrical tooth-gap cut with asymmetrical rollers (31). The apparatus is very similar to a conventional Grob apparatus except for the considerable difference that the rollers (31) are asymmetrical. It is thus possible, with very modest means, to avoid the hitherto unavoidable inaccuracies, the asymmetrical shape of the rollers contrasting with the symmetrical rollers also customary in the Grob method and with the symmetrical cutting tools used for helical toothing. <IMAGE>
Patent DE-3635885-A1 (DE)
Title: Rolling mill, especially a roller press
Inventor: WEHREN PETER
IPC: B02C4/32
Filed: 1986-10-22
Abstract: In rolling mills, especially roller presses, which are operated at very high pressing pressures, the distribution of forces to the bearing housing and to the rolling elements is not optimum and this has a disadvantageous effect on the life of the bearings. A significant improvement in the distribution of forces to the bearing housings and to the rolling elements of a rolling mill is, however, achieved according to the invention by virtue of the fact that the bearing housings (5) of the fixed roller (1) and the bearing housings (6) of the loose roller (2) are provided with media (10, 12) which distribute the pressing pressures on the side at which the pressing pressures occur during the operation of the rolling mill. The life of the bearings in rolling mills is in this way quite considerably increased. <IMAGE>

Patent DE-3708379-A1 (DE)
Title: Magnet ignition system for a spark-ignition internal combustion engine
IPC: F02P9/00
Filed: 1987-03-14
Abstract: In order to limit the speed of rotation of a magnet transistor ignition system, it is proposed that the collector-emitter path of a transistor (15) be connected in parallel with the primary winding (7) of an ignition armature device (1), the base-emitter path of which transistor (15) is connected parallel to a thyristor (21) which can be controlled by means of the primary winding (7) and a two-terminal network (31) with frequency-dependent impedance. In the event of a predetermined speed-of-revolution threshold being exceeded, the two-terminal network (31) which preferably consists of a capacitor (37) and an adjustable resistor (35) prevents the transistor (15) being tripped when a current pulse is induced and thus prevents a saturated exciter field building up in the ignition armature device (1) for the subsequent production of an ignition spark. <IMAGE>
Patent DE-3709085-A1 (DE)
Inventor: BAEHR THOMAS
IPC: F24D19/10
Filed: 1987-03-19
Abstract: A room which is substantially sealed or sealable from the surrounding atmosphere is conditioned by a plant which has a fluid heating or cooling unit, one or more heat exchangers, conduits which connect the unit with the heat exchanger(s), and a computer which is connected with sensors serving to transmit signals denoting the temperature tV of fluid in the conduit or conduits leading from the unit to the heat exchanger(s), the temperature tR of fluid in the conduit or conduits leading from the heat exchanger(s) to the unit, and the rate m of fluid flow in the conduit or conduits. These signals are used to calculate a so-called load range prevailing in the room in accordance with the equation (tV-tR)xm. The calculated load range is compared with the load ranges of a pattern of load ranges which are characteristic of the plant, and the computer adjusts the unit or a mixing valve in the conduit or conduits leading to the heat exchangers(s) in order to change the value of tV so that the selected value of tV conforms to that which was used to calculate the equivalent load range of the pattern.

Title: Apparatus for displacing long wood during longitudinal cutting by means of band saws
Inventor: BERGVALL JEAN GUNNAR
IPC: B27B29/08
Filed: 1987-03-20
Abstract: An apparatus for displacing long wood during longitudinal cutting by means of band saws is proposed. The apparatus has, in a known manner, a narrow, rigid wood-holding device 7 perpendicular to the cutting plane of the band saws, a clamping device 12, 14 for firmly clamping the wood 2 with respect to the holding device 7 and a mechanical drive 8, 9c for moving the holding device 7 to and fro between a position in front of the band saws and a position behind them. According to the invention, the holding device 7 consists of a low, rail-like beam which is supported 6 movably from below and guided sideways, and the clamping device 12, 14 is mounted and guided separately from this beam. The advantage obtained consists in that the holding device 7 has only a comparatively small mass and nevertheless ensures precise wood guidance during sawing, and in that the apparatus does not obstruct the wood at the end faces, so that a middle cut is also possible. <IMAGE>

Title: Radiation measuring instrument for measuring an ionising radiation
Inventor: REIME GERD
IPC: G01T1/18
Filed: 1987-06-04
Abstract: A radiation measuring instrument for measuring the intensity of an ionising radiation (1) contains in its pulse rate converter a ratio value circuit (11) which forms a ratio of the pulse rate (7) generated by a radiation detector (2) under the effect of this radiation and the pulse sequence (47) generated in a pulse generator (12). Both input signals generate an integration voltage (UV) across an integration capacitor (31) in the ratio value circuit (11), the value of which integration voltage is proportional to the ratio of the pulse rates transmitted to the signal inputs (10, 18) of the ratio value circuit (11). The radiation measuring instrument allows relatively accurate measurements even of the intensity of ionising radiations which are within the range of the intensity (Io) of the natural ionising environmental radiation. <IMAGE>
